The disclosure of a disability and the need for accommodations is an extremely sensitive subject requiring utmost confidentiality. Discussion between the student and faculty member should be protected. Further, your ability to work with the student to ensure equal opportunity in your class to consume knowledge and be fairly tested on course material will largely depend on a positive "work with me" attitude from both parties.
Keep in mind that students do not have to reveal a specific diagnosis to you, but they must do so in our office and provide substantial documentation of the condition.
It is very important, unless the student decides otherwise, that he or she not be
identified as a person with a disability to other faculty, staff or classmates.
For students with obvious disabilities, like wheelchair users, disclosure of the disability cannot be avoided; but students with learning disabilities and/or psychiatric/psychological disabilities are often very sensitive about being identified as a student with a disability. Therefore it is very important that instructors avoid "singling out" such students in the classroom.
